Synthesis of bimetallic nanoparticles has
employed many applications especially as larvicidal agents, these bimetallic
nanoparticles therefore need to be produced via a cost-effective and eco-friendly route. Here, green
synthesis of Ag-Co hybrid nanoparticles obtained from aqueous root extract of
palmyra palm was reported. The hybrid nanoparticles formation was noticed by a
colour change from light pink to light brown and further studied using UV-Vis and FT-IR spectrophotometers. The maximum
absorption wavelength, λmax as determined by the UV-Visible
Spectrophotometer was found to be 420nm. The FT-IR showed the
formation and stabilization of the BMNPs. The nanolarvicidal potency was
evaluated by the application of varying concentration ranging from 5 to 50mg/L against first to fourth instars of larvae
and recording the percentage mortality after 24 hours. Probit analysis showed
the LC50 and
